III. Product Structure
The pneumatic clutch brake comprises several key components:
- Clutch Body: Mounted on the equipment's main shaft, the clutch body features a customizable center hole size (refer to the sample for size range), serving as the clutch's core component.
- Clutch Ear Plate and Brake Ear Plate: Meticulously designed to seamlessly connect to the flywheel and machine body of the equipment. This is achieved through four precision-engineered pins, ensuring the unwavering stability and smooth operation of the clutch and brake-an epitome of durability and reliability.
- Friction Pads (Blocks): These indispensable components are at the heart of the clutching and braking process, expertly facilitating both the transmission and interruption of power. They ensure optimum performance and efficiency, making them a cornerstone of the system.
- Clutch Pins, Brake Pins and Locking Plates: These elements form the backbone of connectivity and fixation within the system. The innovative locking plates, meticulously embedded within pin grooves and secured with screws on the flywheel or machine body, effectively prevent any axial pin movement, ensuring steadfast stability.


IV. Working Principle
(I) Clutching Process
Upon the introduction of external compressed air into the clutch cylinder through the intake hole, the piston is propelled into action. This movement, in concert with friction pads, the clutch body, and a flat key, facilitates the rotation of the driven part, seamlessly realizing clutch engagement and enabling robust power transmission.

(II) Braking Process
Upon cessation of air supply, springs promptly activate the piston to move oppositely, rapidly engaging the friction pads, clutch body, and flat key, thus ensuring swift braking of the driven part. Astonishingly, this braking process unfolds in a mere 0.01 - 0.02 seconds, guaranteeing the equipment halts with remarkable speed and precision.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
The installation precision is paramount-holes for the four pins must adhere to a stringent H7 tolerance, with centers parallel to the main shaft center, thereby ensuring impeccable installation accuracy and enduring stability of the pins.

(II) Geometric Tolerance and Roughness Requirements
All geometric tolerances and surface roughness specifications for the center hole and keyway must uncompromisingly align with national standards. Similarly, the geometric precision and surface quality of the customer's main shaft must meet designated criteria to elevate the product's overall performance and reliability.

(III) Installation Sequence Suggestions
Installation flexibility is key-customers may adapt the sequence based on situational needs. A recommended approach is beginning with the installation of clutch and brake ear plates, pins, and locking plates, followed by the clutch brake body, ensuring a streamlined and successful assembly process.

(IV) Installation Notes for Square Pins
Square pins are ingeniously utilized to counteract any potential installation size discrepancies between two pins and mitigate thermal deformation of the plate from clutch heating. It is crucial to ensure that the two flat surfaces of the square pin maintain angular precision, remaining parallel to the radial direction of the ear plate.

(V) Sealing Requirements for Axial Air Intake
For axial air intake configurations, it is essential to securely install sealing caps at both ends of the clutch. This precaution prevents any gas leakage, thus preserving the integrity and efficiency of the airflow system.

(VI) Check after Installation
A thorough post-installation check is imperative-the ends of the clutch and brake must move without restriction to guarantee the unfaltering operation of the clutch and brake system, ensuring peak performance and safety.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Every Kb2100 Air Clutch crafted by Shandong Tenord Machinery Equipment Co., Ltd. is subject to rigorous quality control measures. It is essential that customers refrain from unauthorized disassembly. Any damages originating from such actions will not be covered by our company. In case of encountering any quality-related issues, prompt communication is encouraged, allowing us to swiftly address and resolve your concerns.

(II) Friction Pad Replacement Method
The friction pads are vital yet consumable elements that need replacement after extended usage, especially when showing significant wear. Our design ensures a hassle-free replacement process without the need to disassemble the ear plates or clutch. The steps are straightforward:
- Replacement without Air Supply: Begin by loosening the clutch ear plate. Proceed to remove the bolts and nuts securing the friction pads, replace them with new ones, and securely tighten the bolts and nuts back in place.
- Replacement with Air Supply: Loosen the brake ear plate and follow the same procedure, ensuring a seamless replacement of friction pads.

(III) Timing for Friction Pad Replacement
- For machinery like presses, if the equipment fails to achieve its rated capacity, inspect the condition of the friction pads as they may require replacement.
- Should the wear on the friction pads surpass half the thickness of new ones, it is crucial to replace them promptly to maintain optimal performance.

VII. Product Selection
Selecting the right clutch for your equipment is pivotal in ensuring functionality and efficiency.
- Consequences of Improper Selection: An undersized clutch may not deliver the necessary power, while an oversized clutch can escalate costs and contribute to overheating, hastening wear on friction pads and aging of seals.
- Selection Suggestions: Customers are encouraged to reference our detailed sample catalogs or consult with our skilled technicians who are ready to offer tailored recommendations, ensuring you make the most informed decision.

VIII. Safety Precautions
(I) Protection during High - speed Rotation
Avoid placing hands or objects near the clutch when it is rotating at high speed to prevent injury.

(II) Protection from High Temperature
Direct contact with the clutch immediately post operation is strictly prohibited to prevent burns-ensure you wait approximately half an hour for temperatures to normalize before proceeding with maintenance.

(III) Side Protection
Standing beside a rotating clutch is hazardous due to potential projectiles. It is imperative to have a protective cover in place during operation to safeguard against accidents.

(IV) Attention during Ventilation Operation
During the ventilation and air-stopping processes, keep fingers away from the friction pads to prevent the risk of injury from being pinched.

(V) Safety of Internal Structure
The internal springs of the clutch are best left undisturbed unless handled by professionals, as unauthorized disassembly might lead to injury. Always seek expert assistance for any necessary internal examinations or repairs.
